markstream-vue

Markstream renders Markdown that is still arriving, the way ChatGPT-style apps show text streaming in token by token. Normal Markdown renderers choke on half-finished input, a code fence with no closing backticks, a broken table. Markstream renders it cleanly as it streams and fixes up the formatting as more arrives. It ships separate packages for Vue and Nuxt, React and Next.js, Svelte 5, Angular, and even Vue 2, so most frontends are covered. MIT licensed and free.

There is nothing to host. It is a frontend library you install with your package manager and drop a component into your app. The work is in the integration, not the ops. It handles the hard parts of streaming UIs: virtual windowing so long chats stay fast, progressive Mermaid diagrams and KaTeX math that render as the syntax completes, and Monaco editor hooks for live code blocks. Safe HTML rendering is configurable. The feature surface is wide, so expect to read the docs for the pieces you actually need.

For anyone building an AI chat or assistant UI, this solves a real and annoying problem and costs nothing. Solo, small team, or large, the calculus is the same: install it, free.

The catch: it is a rendering library, not a chat framework. You still wire up your own streaming transport, state, and backend. Markstream only paints what arrives.
